"House of Lies" cast members Ben Schwartz and Josh Lawson are veterans of the Los Angeles improv scene -- co-stars Don Cheadle and Kristen Bell, not so much. But in the unusual special below, the four ditched their characters to join comedians Lauren Lapkus, Ryan Gaul and Eugene Cordero, who also appear in the upcoming third season of the management consultant series, for some long-form improv at L.A.'s Upright Citizens Brigade Theatre. "House of Lies Live!" airs on Showtime tomorrow, December 31st at 10pm, but you can watch it in full online below. Season three of "House of Lies" kicks off January 12th.
